CARBURETOR CONSTRUCTION.

Application. filed September 9, 1927.

lvly invention relates to improvements in carburetor constructions. andit consists in the combinations, constriu-tions and arrangements hereindescribed, and claimed.

An object of my invention is to provid t means whereby all leaking orflow of liquid into the carburetor of an internal combustion engine maybe stopped.

A further object of my invention is to provide a device of the typedescribed in which this means may be actuated from the instrument boardof the automobile.

A further object of my invention to provide a device of the typedescribed by means of which great damage would be prevented fromhappening to the automobile should the automobile catch on tire thesupply of gasoline is completely shut oil from the carburetor.

A further object of my invention is to pro Vide a device of the typedescribed which will also aid in preventing the automobile from beingstolen as the automobile could only be driven a short distance until thegasoline in the carburetor is consumed and the automobile would thenstop, owing to the fact that the supply of gasoline is shut off from thecarburetor.

Other objects and advantages will appear in the following specification.and the novel features oi the invention will be particularly pointed outin the appended claim.

My invention is illustrated in the accompanying drawings. forming partoi this application, in which Figure 1 is a sectional view of my deviceas applied to a carburetor, and

Figure 2 is a section along the line 2 -2 of Figure 1.

In carrying out my invention, I make use of a carburetor 1 having afloat 2 and a valve 3 arranged to engage with a 'alve seat 4 for closingthe passage in the supply pipe 0.

I provide a. housing 6 having a weight 7 movably disposed therein. Aresilient rod 8 is rigidly secured to the weight 7 and extends upwardlythrough the housing 6 and through a flexible tube 9 and aninstrumentboard it). A button or knob 11 is rigidly secured to the freeend of the resilient rod 8.

Serial No. 218,517.

The housing 6 is disposed in alignment with the valve 3. A spring 12 isdisposed in the housing (5 concentric with the resilient rod 8 betweenthe upper end of the housing and the weight 7. A latch member 13 ispivotally secured at 1 1 to the instrument board it) for a purposehereinafter described.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The float 52 and alve 3simulate an ordinary float valve of an ordinary carl'iuretor 1. Thefloat valve is adapted to permit a predetermined amount of gasoline toenter the carburetor through the teed pipe 5. Let us assume that theuser wishes to park the car. By moving the locking member 13 to one sideabout its pivot. the weight 7 may be moved downwardly into engagementwith the vaive 3 by pressing the knob 11 and by the aid oi? the spring12. By forcing the weight 7 downwardly as far as possible, the valve 3will be forced into engagement with the alve seat 4, thus positivelyclosing the passageway in the feed pipe 5. The spring 12 is suiiicientto hold the weight 7 in ei'igagementwith the valve 3, thus preventingthe passage of gasoline into the carburetor.

The weight 7 may be removed from the valve 3 by pulling outwardly uponthe knob 11 a suilicicnt distance to allow the locking member 13 tofreely move between the knob and the instrument board. It is obviousthat carburetors differ in construction. However. in the ditterentcarburetors the flow oi" the gasoline into the carburetors is controlledby valves which are actuated by floats. 'lhcretore, the structure mayvary to agree with the various types of carburetors without departingfrom the spirit and scope of the invention.

. t will be understood that my device may be embodied in. oldcarburetors as well as new, and may be attached to the ignition switch.whereby it will be operated automatically.

I claim:

The combination with a carburetor and an instrument board, a i'eed pipefor said carblu'etor, and a float valve arranged to vary the amount ofliquid passing into said carburetor. ot a weight member a rrangcd toltltl engage With said flout valve for actuating :id float valve forpositit'el stoppin; the How of liquid into said (:m'buretor, a resilientrod having one end secured to said weight member, a knob secured to theother end of said resilient rod, said resilient rod extending throughsaid instrument board.

and a member pivotally mounted upon said instrument board and arrangedto he passed heneath said knob For holding said resilient 10 rodoutwardly and for holding said weight member away from said Valve.
